Question

how to solve this : Find the matrix P associated with the change from basis {e1, e2, e3} in R^3 to basis {u1, u2, u3} in R^3 , u1=(1 1 0)^T , u2=(0 1 1)^T , u3=(1 0 1)^T

Answer 1

i believe what you do is make a matrix with u1, u2, and u3 as its columns, then find its inverse. that matrix would give you the change of basis coordinates....i think <.<

Answer 2

im assuming that e1, e2 and e3 are the standard basis vectors.
